and second rings. The station set processes the data and sends an ID message
to the display. The calling number ID data sent from the PBX to the station set
differs from the calling number ID data presented on the display.

When placing a call to another extension, the called number ID (by default,
the extension of the telephone being called) is shown in the display.

Both the calling and called number IDs can be retrieved using the
d42_gtcallid( ) function. The d42_gtcallid( ) function retrieves the
called/calling number ID message sent from the PBX to the station set, not the
data sent to the display. Refer to the Dialogic

application will maintain functionality across different
manufacturers’ switches.
